Hi @haejin, sorry to both you. I just noticed that you haven't claimed your free Byteball tokens from the airdrop yet. All you need to do to claim your tokens is verify your Steem account using SteemConnect.

Here is a post with instructions:
Steem's Byteball Airdrop Instructions

With your reputation, you would get $160 worth of Byteball tokens: $80 liquid (available to cash out right away). The other $80 worth is unlocked after one year.
